☀️ Node Configuration

0gchaind config chain-id zgtendermint_16600-2
0gchaind config keyring-backend os
0gchaind config node tcp://localhost:56657

☀️ Initialize the Node

NOTE: Replace NODE-NAME with your desired node name.

0gchaind init NODE-NAME --chain-id zgtendermint_16600-2

☀️ Update Genesis and Addrbook

rm ~/.0gchain/config/genesis.json
curl -Ls https://github.com/0glabs/0g-chain/releases/download/v0.2.3/genesis.json > $HOME/.0gchain/config/genesis.json

☀️ Add Seed Nodes

PEERS="80fa309afab4a35323018ac70a40a446d3ae9caf@og-testnet-peer.itrocket.net:11656,...(other peers)..."
SEEDS="[email protected]:26656,...(other seeds)..."
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.0gchain/config/config.toml

☀️ Set Gas and Pruning

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.0gchain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.0gchain/config/app.toml

sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.0gchain/config/config.toml

☀️ Indexer Configuration

NOTE: If you're setting up a storage node, you might not want to set this to null.

sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.0gchain/config/config.toml

☀️ Set Ports

echo "export G_PORT="56"" >> $HOME/.bash_profile
source $HOME/.bash_profile
sed -i.bak -e "s%:1317%:${G_PORT}317%g; s%:8080%:${G_PORT}080%g; s%:9090%:${G_PORT}090%g; ..." $HOME/.0gchain/config/app.toml
sed -i.bak -e "s%:26658%:${G_PORT}658%g; s%:26657%:${G_PORT}657%g; ..." $HOME/.0gchain/config/config.toml

☀️ Snap Installation

🚨🚨🚨 Don’t forget to back up your priv_validator_key.json file located inside the config folder. 🚨🚨🚨

NOTE: If you want to use your own RPC on your storage node you have to use snapshot start from blockheight 0

screen -S 0g
sudo systemctl stop 0gchaind
0gchaind tendermint unsafe-reset-all --home $HOME/.0gchain --keep-addr-book
cp $HOME/.0gchain/data/priv_validator_state.json $HOME/.0gchain/priv_validator_state.json.backup
curl -L https://vps5.josephtran.xyz/0g/0gchain_snapshot.lz4 | sudo lz4 -dc - | sudo tar -xf - -C $HOME/.0gchain
mv $HOME/.0gchain/priv_validator_state.json.backup $HOME/.0gchain/data/priv_validator_state.json

☀️ Start the Node
